I am studying a chiller and generator located outside a building, The ambient temperature is 20 C, the Chiller fans are discharging at 55 C, and also the generator is discharging at 55 C. The study shows the full domain is at the same temperature around 55 C, however, it's expected to be ambient except around the chiller and generator, this means that the generator inlet and outlet are at the same temperature.
could anyone help solve this issue?
I am confused about whether to consider auto-forced convection or not consider
